From facing Carrefour (which is now Migros!) walk through to the front of Migros & turn right, continue until the start of the one way system, turn left ie with the one way & first right into the Paspatur, just by the Nicholas Homes bureau de change. That'll bring you to the Megri.
Not quite sure which boutiques you're looking for, but there are loads in the road almost opposite the one to the Paspatur where I'm sending you.
